Wow this video just made me realize A.) how much I forgot since I graduated, and B.) how much I haven’t needed to remember any of this so far in my professional developer career
so you mean these doesn't apply to your working experience. I am a student and I saw some competition problems like these and couldn't solve some. Then I thought that what will I do when I got a job?
@@makima7457 no, your job doesn't require this. However, it just improves your understanding of coding overall. If you are very good at leetcode, then employers can be confident in you. It shows employers that you have the discipline t to learn any skills required for a job.
@@makima7457 These kind of problems improve our problem solving abilities. That's why we learn / practice these pattern. In professional career, there not many situations where you need to use these patterns as there are already templates given. We just need to know how to use them accordingly.
I am still under 200 problems solved but I think I'm already qualified enough to say that this video is exactly the advice I would give too. The 80/20 rule... that 8 patterns will help you solve about 70% of mediums with the caveat that you DEEPLY understand the patterns and all the possible subtle variations. The other 30% are either different algorithms, tricks / math knowledge, greedy algorithms or DP problems... but most DP problems can be solved well enough with DFS + top-down memoisation.
Its one thing to master solving these problems. But its completely different story when it comes to identify these patterns in real world problems or modelling real issues with these data structures.
I just discovered your channel after 4 months in a basic Python and intro to data science. During the course, I've written a few programs to automate tasks at work. I'm deciding where to go next and the most efficient way to get there. This channel is awesome! It has put so much into the right context to make the next decision.
Striver has already made series on each pattern with problems. Check it out on his channel #takeUforward, course name - Strivers A2Z DSA Course. He is the best.
Hi, I really admire your content which is unique and worth, could please make sure that after every new method maintain few seconds time so that we can process it. Actually your words have clarity only transition of topics need a little gap
Can you please tell me if it is important to slove competitive programming questions ? Is it important to my career. I am good at coding and problem solving but don't slove hard questions
Highly misleading, came to see patterns but saw generic DS& Algo script , patterns are there, what matters is the patterns that build from intuitions not concepts
I am taking CS50, Introduction to Programming with Python. Sometimes, when I try to solve problems, I can't figure them out. I might understand the logic, but struggle with implementing it. After attempting to solve the problem myself, I often have to look at the solution. When I do, I understand it. Does this mean I'm a bad programmer, or that programming isn't for me?
It's always Ok to look at the solutions. But Make sure you understand the solution. But do revisit the problem the try solving it again, this time maybe chose a different language (any lang works, it's good to know more languages).
please should learn DS and algo to build big stuff and give it to open-source problem with Indian developers learn DS just to crack interviews thats why there is no Indian big open source community which has build some extreme stuff like Database, streaming solution, or compilers or anything not even a framework
Sir, I am a data science enthusiast I have covered all the mathematics behind machine learning, practice the implementation and did same for deep learning also. I started NLP please guide me towards this role I want to get a good job this placement season it will start later this year kindly guide
@@Simple_OG I disagree, doing something yourself if good for reaching "depth" like a path in a DFS. Doing a course/reading a book is like a BFS in a given domain. It gives you the overview and wires the concepts together. So, you need both.

Its one thing to master solving these problems. But its completely different story when it comes to identify these patterns in real world problems or modelling real issues with these data structures.
Once you've solved enough of each pattern, you can reduce any given problem to the basis (some "ideal", simple problem).

Several great easy takeaways from this video and I’ve only watched it once. I’ll implement bisect left and right in swift now lol. Love it, thanks

This video is mind-blowing !!!
Sir, Why don't you start a series on each pattern???
It would be useful for everyone even though it is paid 🙏
Striver has already made series on each pattern with problems.

Hi, I really admire your content which is unique and worth, could please make sure that after every new method maintain few seconds time so that we can process it. Actually your words have clarity only transition of topics need a little gap
happy to see you, love from Bangladesh ❤
Are you a software engineer in Bangladesh?
this video is only useful for those that have already solved enough of those Leetcode problems
I love you Sahil!!! Your journey inspired me to apply for a masters in computer science at Northeastern University!!!
I practices a lot of leetcode but my brain feels frozen right now and I cannot write any code even if I know the approaxh
How many problems you have practiced?
Me too
More like 40%, to solve another 50% to be at the desired 90% you need only 35 more patterns.
what are those patterns and where to know them from?
What are those 😊
It would be great if you could share curated questions list for each pattern for practice
look up Neetcode
can you share list of problems in each pattern to practice? That would be very helpful, Thanks
I'm so gonna consume these patterns into my soul.
Thank you such a great video that doesn't take 1 hour.
Thanks for providing the advice regarding the bisect module functions.
People from India 🎉
Hashmap is pretty important too
Thanks for useful content!!
As someone commented earlier - Bro talks in lowercase 🤣🤣🤣
I am always looking for your new videos ❤
Please tell us about how to start leetcode for beginners
Too valuable. Thanks Sahil❤
Can you please tell me if it is important to slove competitive programming questions ? Is it important to my career. I am good at coding and problem solving but don't slove hard questions
That was really insightful ❤
Greater explanation
Thank you Sahil ❤

Which is the best course to learn DSA and their time complexities?
i love your videos😍
Thank you❣
Nice video❤
Hard to digest in 8 minutes make detailed video.

Prefix array, hashing are add-on
Hi Sahil...sometimes I feel difficulty in thinking logic...I think it will improve over time by solving many problems. I don't know if I am right ?
Solve sudoku.. and other corelated ones.
Sure I will start solving now. Thanks alot
Very good
Great knowledgeable video❤
You have to implement it too
How to learn to solve subset and substring problems? Can you please guide
How do you create such animations?
Good for revision
you inspired me sahil. btw how did you get 300K package? is it your negotiation skills or due to COVID you got a high package? please tell me
I subscribed to the interviewmaster mailing list. But no mail is delivered.
Amazing
Me after listening to him: may be bro is very serious person in life
Me after seeing thumbnail: may be not 🤔
Finally you've uploaded a video
good video bro..could you please suggest me DSA course for golang
thanks a lot
Thank you.....🔥🔥🔥
Valuable video
your voice awesome
bro is like sidhi baat no bakwas
Sir, I am a data science enthusiast I have covered all the mathematics behind machine learning, practice the implementation and did same for deep learning also.
I started NLP please guide me towards this role I want to get a good job this placement season it will start later this year kindly guide
Thank you Sir
please make complete courses on devops, cloud computing.
Stop watching courses do something with yourself
@@Simple_OG I disagree, doing something yourself if good for reaching "depth" like a path in a DFS. Doing a course/reading a book is like a BFS in a given domain. It gives you the overview and wires the concepts together. So, you need both.
Suprised DP patterns is not on the list.
Please make a video on Salesforce Developer path
The legend!
Are you a front-end / back-end developer or something else?
Can you please tell how to improve logical and critical thinking skill??
Hai.you should solve sudoku and logical problems which are available free on internet
By practicing.
bro whats difference betn 2 pointer and a sliding window
Which software do you use for animation?
Can you please make video on Salesforce developer path.
What about UnionFind?
Is it in the topological sorting?
Thank you Sahil anna
Thanks
can you please share tools used to create these content
Bro can u make a video on doing a project on git hub for beginners plss
я удивлён тем, что много чего из этого списка есть в ЕГЭ
Sir I didn't understand leetcode problem what can do please help.
Sor I want to know is currently there scope in the industry because there is massive layoff please help me I have to prepare.
But the patterns will have subpatterns
I am from a very small village in Bihar. I am 19 years old and I don't even know how to operate a computer. Can i became a good software engineer?
Yes
All this is good until DP and Graphs come into play :P
6:18
Should we do DSA in JavaScript
Can do in any language JS is popular because its the backbone of web
I am bigger python can i join your course are not
Where is DP?
DP is no tmentioned?
I want to be an AI engineer which topics should i learn durinh my BSC beside DSA
where's dynamic programming? 💀
What about dynamic programming and graphs ?
That's the remaining 20%
